▎ 摘 要
NOVELTY - The utility model claims a longitudinal high heat-conducting graphene combined structure, comprising: graphene foam block: at least one hole is set on the graphene the hole passes through the foaming graphene; graphene foam column, the foam column graphene set in the hole along the axial direction. The longitudinal high heat-conducting graphene combined structure of the utility model has no adhesive or filler, and the horizontal thermal conductivity is 800 ~ 1600W/m-K, the longitudinal thermal conductivity is 20 ~ 200W/m-K, the performance is excellent.
